| Make | Model Ch. | Symptom | Problem Solution | Solution | By: |
|---|---|---|---|---|---|
| Sony | BE3D | Picture too big, maybe strange colors, shuts down after a few seconds | Check for shorts in IC606 9V voltage reg | ||
| Sony | BE3D | Procedure to enter the service mode | Press standby, i, 5, vol+ and tv TT should now be displayed on the screen indicating the set is in the service mode | ||
| Sony | KV28WS2U BE3D | St/by LED flashes twice | M24C32 sm EEPROM replaced (caused by crt flashover?) | ||
| Sony | KV28WS2U BE3D | Service mode entering | from st/by press OSD/5/volume+/tv; TT____ will appear top right. Entering TT38 sets the TV as a 28 inch, TT24 sets TV as PAL I, TT79 for widescreen. MENU gives submenu choices eg geometry; TT00 exits & stores | ||
| Sony | BE3D KV32WF1U | Serrated line at top & bottom of screen | Fit improved line driver trfmr pt no 1-437-090-31 | ||
| Sony | BE3D KV32WF1U | DEAD WITH POWER SUPPLY SCREAMING | REPLACE LINE O/P TRANSISTOR Q802 | ||
| Sony | BE3D KV32WF1 | NO SOUND | REPLACE IC1200, PS602, Q1200 AND Q1201 | ||
| Sony | BE3D KV29F2U | Height excessive varies with pic content then collapses aft 3 mins shuts down with LED flashing error 2 | IC606 LM2940CT 9V regulator s/c from input to output in PSU secondary, thus the +9V line was high and varied with picture content. | ||
| Sony | BE3D KV28WS2U | St/by only LED flashes error code 2 | LOPTx can be cause, confirmed by measuring volts coll Q606 in prot cct. If it rises to 11v LOPTx faulty (should be 0v) - then enter serv mode & disable prot (see other entry). | ||
| Sony | BE3D KV28WS2U | St/by only LED flashes error code 2 | Instead of replacing the EEPROM try the following - Whilst LED is flashing enter serv mode (St/by, I, 5, vol+ & TV). This disables prot & set comes on with "TT--" . Press "0, 8" on R/C which will clear error buffer. | ||
| Sony | BE3D KV28WS2U | LED successively flashes twice | M24C32-MW6T EPROM IC2 - 8 leg sm device pt no 875952494 | ||
| Sony | BE3D KV28WS2U | LED flashes twice aft LOPTx replacement to cure dead set | Check EEPROM 24C32 in IF sound module by replacement. Enter service mode & at TT promt enter country code 24 (UK system) - prevents need for setting each chan band when tuning | ||
| Sony | BE3D KV28WS2U | EEPROM corruption | Caused by flashover of red gun in crt - crt replaced under warranty (if lucky) | ||
| Sony | BE3D KV28WS2U | Dead at sw on - will produce a click from relay after a period of time. When G2 advanced, line collapse noticed | Check for dry joints around scan coils plug, check R870M for o/c 1R, 1w | ||
| Sony | BE3D KV28WS2U | BUZZING NOISE THROUGH SPEAKERS | CHECK EARTH CONNECTION ON CN303 PLUG FOR O/C OR DRY JOINT | ||
| Sony | BE3D KV28WS2U | At sw on reverts to st/by with LED flashing twice | Measure volts at collector Q606 (located in the middle of the PCB towards the right edge), if it stays at 0V, then you need to replace or re-set the EEPROM, if it goes high - then overcurrent protection is activated, suspect faulty LOPT. After replacing the LOPT, collector Q606 should stay at 0V and the set should come on, however with some software versions, the error code 2 will remain in the memory and you need to clear it manually.To clear the error code from the EEPROM you can replace it with a blank one, but it is much easier just to re-set it. While your error code 2 is still flashing, press on the remote control: [5], [-/--], [5], [9], [Standby], [i], [5], [vol+], [TV]. The set will come on in the service mode with TT-- on the screen, press [MENU] and write down all the settings for picture, geometry and sound. Then press [MENU] again to return to TT-- screen. Enter 49 to clear the EEPROM, and switch the mains off. Now go back to the service mode (TT-- on the screen), enter 24 to set destination "UK", then press [MENU] and enter all the settings what you have written down. The sequence [5], [-/--],[5],[9] sets the TV on program 59; the sequence [Standby], [i], [5], [vol+], [TV] is used to enter the service mode. In order to execute the command TT49 (re-set EEPROM), the TV must be on program 59. | ||
| Sony | BE3D KV28WS2 | VOLUME VARIES, CHANNELS WIPE FROM MEMORY, UNUSUAL CHARACTERS DOWN SIDE OF SCREEN | REPLACE IC3 WITH PREPROGRAMMED NEW TYPE | ||
| Sony | BE3D KV25X1U | LED flahes 19 times at sw on | Multiple devices not acknowledging - Fuse PS603 o/c | ||
| Sony | BE3D KV25X1U | E/W faulty | Q800 in pin cush out cct leaky | ||
| Sony | BE3D KV24WX1U | Whine from lh chan over normal sound, same on phone & scart skt - RH chan ok | Sus MSP chip IC202 on "A" board with tuner. As this is a 60 pin sm chip & expensive the good chan was linked to both o/ps |
